概括
多种牧场增强了牛肉的营养, 这些营养物质转移到人类身上, 在消费后改变它们的新陈代谢特征, 将料与消费者健康联系起来.
科学领域:
- 营养科学
- 代谢学
- 动物科学
背景情况:
- 来自各种草本的代谢物可能会影响放牧牛肉质量和人类健康.
- 了解这些化合物在食物层中的转移至关重要.
研究的目的:
- 为了比较三个不同的牧场系统的Angus牛的代谢特征.
- 评估牧场衍生代谢物在牛肉消费后对人体血的影响.
主要方法:
- 安格斯牛在多年生麦草/白叶三叶草 (PRG),复杂多物种 (CMS) 或邻近单一种植带 (AMS) 的牧场上完成.
- 分析了牛肉饼,并对人类参与者进行了双盲随机临床试验,评估了食后的血代谢量.

Biodiversity and Human Values
14.8K
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Plant Breeding and Biotechnology
17.2K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Defenses Against Pathogens and Herbivores
21.6K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Synthetic Biology
4.4K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Overview of Metabolism
25.7K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Transduction
3.0K
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome...
